Figure Out the Length of Text in a Column in MySQL

Considering the following table STOCKPRICE and its details.

CREATE TABLE `STOCKPRICE` (`ID` INT(11) NOT NULL,`NAME` TEXT NOT NULL COLLATE 'utf8_bin',`PRICE` INT(11) NOT NULL)COLLATE='utf8_bin'ENGINE=InnoDB;

Also, use the following to create sample data as below.

INSERT INTO `STOCKPRICE` (`ID`, `NAME`, `PRICE`) VALUES (1, 'ABC Ltd', 15);INSERT INTO `STOCKPRICE` (`ID`, `NAME`, `PRICE`) VALUES (2, 'XYZ Ltd ', 19);INSERT INTO `STOCKPRICE` (`ID`, `NAME`, `PRICE`) VALUES (3, 'AAA Ltd', 16);

Now, you can find out the length of the text in the NAME column:

SELECT LENGTH(NAME) LENGTH FROM STOCKPRICE, which will result in the following values+ -- -- -- -+|LENGTH |+ -- -- -- -+| 7 || 8 || 7 |+ -- -- -- -+

Also, you can use the TRIM function to remove the extra spaces. SELECT LENGTH(TRIM(NAME)) LENGTH FROM STOCKPRICE, which will result in the following values. Please note the change in the value for row 2:

+ -- -- -- -+|LENGTH |+ -- -- -- -+| 7 || 7 || 7 |+ -- -- -- -+
